Abstract

An assembled hip roof includes a plurality of roofing panels as well as the rafters of the underlying structure that support those panels. Ridge caps preferably extend over the panels at the hip rafters. In a preferred embodiment, a set of metal roofing panels is designed and shaped for use on a specific hip roof configuration, using a minimal number of separate panels. In a preferred embodiment especially suitable for larger area roofs, a plurality of the panels interlock with one another. The panels are preferably coated on one or both sides for protection against scratching during handling and assembly. One or more of the panels preferably include decorative relief, such as the appearance of overlapping wooden boards. In a preferred embodiment of the method of the invention, the panels are manufactured from rolled steel. Plastic coating is preferably applied to the rolled steel after it is painted and before the steel is cut into panels and given decorative relief, in order to protect the panels from damage.
